The young Georgiana is contracted in marriage to William Cavendish, Duke of Devonshire, with the expectation that she produce his male heir. Georgiana is quickly disillusioned by her husband, especially when Charlotte, a motherless child, comes to live with them while Georgiana is pregnant. William expects Georgiana to tolerate the child's presence, who turns out to be his own illegitimate offspring. He also suggests that she "practise mothering" on the young girl. When Georgiana gives birth to a girl, William is displeased. In his mind, he has fulfilled his obligations to her as her husband but, by failing to provide him with a legitimate male heir, she has failed in her obligations as his wife.
